No. 14/113,537, filed Aug. 30, 2016, which is a National Stage ofInternational Application No. PCT/US2012/040990, filed Jun. 6, 2012,which claims priority to U.S. Application Ser. No. 61/494,667, filedJun. 8, 2011, the disclosures of which are incorporated herein byreference in their entirety.

FIELD OF THE INVENTION

The present invention relates to novel heteroleptic iridium carbenecomplexes. In particular, these iridium complexes are phosphorescent andare useful as emitters in OLED devices.

BACKGROUND

Opto-electronic devices that make use of organic materials are becomingincreasingly desirable for a number of reasons. Many of the materialsused to make such devices are relatively inexpensive, so organicopto-electronic devices have the potential for cost advantages overinorganic devices. In addition, the inherent properties of organicmaterials, such as their flexibility, may make them well suited forparticular applications such as fabrication on a flexible substrate.Examples of organic opto-electronic devices include organic lightemitting devices (OLEDs), organic phototransistors, organic photovoltaiccells, and organic photodetectors. For OLEDs, the organic materials mayhave performance advantages over conventional materials. For example,the wavelength at which an organic emissive layer emits light maygenerally be readily tuned with appropriate dopants.

OLEDs make use of thin organic films that emit light when voltage isapplied across the device. OLEDs are becoming an increasinglyinteresting technology for use in applications such as flat paneldisplays, illumination, and backlighting. Several OLED materials andconfigurations are described in U.S. Pat. Nos. 5,844,363, 6,303,238, and5,707,745, which are incorporated herein by reference in their entirety.

One application for phosphorescent emissive molecules is a full colordisplay. Industry standards for such a display call for pixels adaptedto emit particular colors, referred to as “saturated” colors. Inparticular, these standards call for saturated red, green, and bluepixels. Color may be measured using CIE coordinates, which are wellknown to the art.

One example of a green emissive molecule is tris(2-phenylpyridine)iridium, denoted Ir(ppy)₃, which has the following structure:

In this, and later figures herein, we depict the dative bond fromnitrogen to metal (here, Ir) as a straight line.

As used herein, the term “organic” includes polymeric materials as wellas small molecule organic materials that may be used to fabricateorganic opto-electronic devices. “Small molecule” refers to any organicmaterial that is not a polymer, and “small molecules” may actually bequite large. Small molecules may include repeat units in somecircumstances. For example, using a long chain alkyl group as asubstituent does not remove a molecule from the “small molecule” class.Small molecules may also be incorporated into polymers, for example as apendent group on a polymer backbone or as a part of the backbone. Smallmolecules may also serve as the core moiety of a dendrimer, whichconsists of a series of chemical shells built on the core moiety. Thecore moiety of a dendrimer may be a fluorescent or phosphorescent smallmolecule emitter. A dendrimer may be a “small molecule,” and it isbelieved that all dendrimers currently used in the field of OLEDs aresmall molecules.

As used herein, “top” means furthest away from the substrate, while“bottom” means closest to the substrate. Where a first layer isdescribed as “disposed over” a second layer, the first layer is disposedfurther away from substrate. There may be other layers between the firstand second layer, unless it is specified that the first layer is “incontact with” the second layer. For example, a cathode may be describedas “disposed over” an anode, even though there are various organiclayers in between.

As used herein, “solution processible” means capable of being dissolved,dispersed, or transported in and/or deposited from a liquid medium,either in solution or suspension form.

A ligand may be referred to as “photoactive” when it is believed thatthe ligand directly contributes to the photoactive properties of anemissive material. A ligand may be referred to as “ancillary” when it isbelieved that the ligand does not contribute to the photoactiveproperties of an emissive material, although an ancillary ligand mayalter the properties of a photoactive ligand.

As used herein, and as would be generally understood by one skilled inthe art, a first “Highest Occupied Molecular Orbital” (HOMO) or “LowestUnoccupied Molecular Orbital” (LUMO) energy level is “greater than” or“higher than” a second HOMO or LUMO energy level if the first energylevel is closer to the vacuum energy level. Since ionization potentials(IP) are measured as a negative energy relative to a vacuum level, ahigher HOMO energy level corresponds to an IP having a smaller absolutevalue (an IP that is less negative). Similarly, a higher LUMO energylevel corresponds to an electron affinity (EA) having a smaller absolutevalue (an EA that is less negative). On a conventional energy leveldiagram, with the vacuum level at the top, the LUMO energy level of amaterial is higher than the HOMO energy level of the same material. A“higher” HOMO or LUMO energy level appears closer to the top of such adiagram than a “lower” HOMO or LUMO energy level.

As used herein, and as would be generally understood by one skilled inthe art, a first work function is “greater than” or “higher than” asecond work function if the first work function has a higher absolutevalue. Because work functions are generally measured as negative numbersrelative to vacuum level, this means that a “higher” work function ismore negative. On a conventional energy level diagram, with the vacuumlevel at the top, a “higher” work function is illustrated as furtheraway from the vacuum level in the downward direction. Thus, thedefinitions of HOMO and LUMO energy levels follow a different conventionthan work functions.

More details on OLEDs, and the definitions described above, can be foundin US Pat. No. 7,279,704, which is incorporated herein by reference inits entirety.

DETAILED DESCRIPTION

Generally, an OLED comprises at least one organic layer disposed betweenand electrically connected to an anode and a cathode. When a current isapplied, the anode injects holes and the cathode injects electrons intothe organic layer(s). The injected holes and electrons each migratetoward the oppositely charged electrode. When an electron and holelocalize on the same molecule, an “exciton,” which is a localizedelectron-hole pair having an excited energy state, is formed. Light isemitted when the exciton relaxes via a photoemissive mechanism. In somecases, the exciton may be localized on an excimer or an exciplex.Non-radiative mechanisms, such as thermal relaxation, may also occur,but are generally considered undesirable.

The initial OLEDs used emissive molecules that emitted light from theirsinglet states (“fluorescence”) as disclosed, for example, in U.S. Pat.No. 4,769,292, which is incorporated by reference in its entirety.Fluorescent emission generally occurs in a time frame of less than 10nanoseconds.

More recently, OLEDs having emissive materials that emit light fromtriplet states (“phosphorescence”) have been demonstrated.

Phys.Lett., vol. 75, No. 3, 4-6 (1999) (“Baldo-II”), which are incorporatedby reference in their entireties. Phosphorescence is described in moredetail in US Pat. No. 7,279,704 at cols. 5-6, which are incorporated byreference.

FIG. 2 shows an inverted OLED 200. The device includes a substrate 210,a cathode 215, an emissive layer 220, a hole transport layer 225, and ananode 230. Device 200 may be fabricated by depositing the layersdescribed, in order. Because the most common OLED configuration has acathode disposed over the anode, and device 200 has cathode 215 disposedunder anode 230, device 200 may be referred to as an “inverted” OLED.Materials similar to those described with respect to device 100 may beused in the corresponding layers of device 200. FIG. 2 provides oneexample of how some layers may be omitted from the structure of device100.

The simple layered structure illustrated in FIGS. 1 and 2 is provided byway of non-limiting example, and it is understood that embodiments ofthe invention may be used in connection with a wide variety of otherstructures. The specific materials and structures described areexemplary in nature, and other materials and structures may be used.Functional OLEDs may be achieved by combining the various layersdescribed in different ways, or layers may be omitted entirely, based ondesign, performance, and cost factors. Other layers not specificallydescribed may also be included. Materials other than those specificallydescribed may be used. Although many of the examples provided hereindescribe various layers as comprising a single material, it isunderstood that combinations of materials, such as a mixture of host anddopant, or more generally a mixture, may be used. Also, the layers mayhave various sublayers. The names given to the various layers herein arenot intended to be strictly limiting. For example, in device 200, holetransport layer 225 transports holes and injects holes into emissivelayer 220, and may be described as a hole transport layer or a holeinjection layer. In one embodiment, an OLED may be described as havingan “organic layer” disposed between a cathode and an anode. This organiclayer may comprise a single layer, or may further comprise multiplelayers of different organic materials as described, for example, withrespect to FIGS. 1 and 2.

Structures and materials not specifically described may also be used,such as OLEDs comprised of polymeric materials (PLEDs) such as disclosedin U.S. Pat. No. 5,247,190 to Friend et al., which is incorporated byreference in its entirety. By way of further example, OLEDs having asingle organic layer may be used. OLEDs may be stacked, for example asdescribed in U.S. Pat. No. 5,707,745 to Forrest et al, which isincorporated by reference in its entirety. The OLED structure maydeviate from the simple layered structure illustrated in FIGS. 1 and 2.For example, the substrate may include an angled reflective surface toimprove out-coupling, such as a mesa structure as described in U.S. Pat.No. 6,091,195 to Forrest et al., and/or a pit structure as described inU.S. Pat. No. 5,834,893 to Bulovic et al., which are incorporated byreference in their entireties.

Unless otherwise specified, any of the layers of the various embodimentsmay be deposited by any suitable method. For the organic layers,preferred methods include thermal evaporation, ink-jet, such asdescribed in U.S. Pat. Nos. 6,013,982 and 6,087,196, which areincorporated by reference in their entireties, organic vapor phasedeposition (OVPD), such as described in U.S. Pat. No. 6,337,102 toForrest et al., which is incorporated by reference in its entirety, anddeposition by organic vapor jet printing (OVJP), such as described inU.S. patent application Ser. No. 10/233,470, which is incorporated byreference in its entirety. Other suitable deposition methods includespin coating and other solution based processes. Solution basedprocesses are preferably carried out in nitrogen or an inert atmosphere.For the other layers, preferred methods include thermal evaporation.Preferred patterning methods include deposition through a mask, coldwelding such as described in U.S. Pat. Nos. 6,294,398 and 6,468,819,which are incorporated by reference in their entireties, and patterningassociated with some of the deposition methods such as ink-jet and OVJD.Other methods may also be used. The materials to be deposited may bemodified to make them compatible with a particular deposition method.For example, substituents such as alkyl and aryl groups, branched orunbranched, and preferably containing at least 3 carbons, may be used insmall molecules to enhance their ability to undergo solution processing.Substituents having 20 carbons or more may be used, and 3-20 carbons isa preferred range. Materials with asymmetric structures may have bettersolution processibility than those having symmetric structures, becauseasymmetric materials may have a lower tendency to recrystallize.Dendrimer substituents may be used to enhance the ability of smallmolecules to undergo solution processing.

Devices fabricated in accordance with embodiments of the presentinvention may further optionally comprise a barrier layer. One purposeof the barrier layer is to protect the electrodes and organic layersfrom damaging exposure to harmful species in the environment includingmoisture, vapor and/or gases, etc. The barrier layer may be depositedover, under or next to a substrate, an electrode, or over any otherparts of a device including an edge. The barrier layer may comprise asingle layer, or multiple layers. The barrier layer may be formed byvarious known chemical vapor deposition techniques and may includecompositions having a single phase as well as compositions havingmultiple phases. Any suitable material or combination of materials maybe used for the barrier layer. The barrier layer may incorporate aninorganic or an organic compound or both. The preferred barrier layercomprises a mixture of a polymeric material and a non-polymeric materialas described in U.S. Pat. No. 7,968,146, PCT Pat. Application Nos.PCT/US2007/023098 and PCT/US2009/042829, which are herein incorporatedby reference in their entireties. To be considered a “mixture”, theaforesaid polymeric and non-polymeric materials comprising the barrierlayer should be deposited under the same reaction conditions and/or atthe same time. The weight ratio of polymeric to non-polymeric materialmay be in the range of 95:5 to 5:95. The polymeric material and thenon-polymeric material may be created from the same precursor material.In one example, the mixture of a polymeric material and a non-polymericmaterial consists essentially of polymeric silicon and inorganicsilicon.

Devices fabricated in accordance with embodiments of the invention maybe incorporated into a wide variety of consumer products, including flatpanel displays, computer monitors, medical monitors, televisions,billboards, lights for interior or exterior illumination and/orsignaling, heads up displays, fully transparent displays, flexibledisplays, laser printers, telephones, cell phones, personal digitalassistants (PDAs), laptop computers, digital cameras, camcorders,viewfinders, micro-displays, vehicles, a large area wall, theater orstadium screen, or a sign. Various control mechanisms may be used tocontrol devices fabricated in accordance with the present invention,including passive matrix and active matrix. Many of the devices areintended for use in a temperature range comfortable to humans, such as18 degrees C. to 30 degrees C., and more preferably at room temperature(20-25 degrees C.).

The materials and structures described herein may have applications indevices other than OLEDs. For example, other optoelectronic devices suchas organic solar cells and organic photodetectors may employ thematerials and structures. More generally, organic devices, such asorganic transistors, may employ the materials and structures.

Many known metal carbene complexes have poor OLED device performance.There are many possible factors can contribute to this poor performance,such as high sublimation temperature of the emitter, long triplettransient lifetime of the emitter, low triplet of the host, unbalancedcharges in the device, etc. In the presently disclosed compounds, twodifferent carbene ligands are used to tune the color and photophysicalproperties in deep blue emitters, making the compounds heteroleptic.Through this approach, different physical properties can be tuned bydifferent set of ligands within a single molecule.

DFT calculations were used to predict the properties of disclosedcompounds and comparative compounds. The HOMO, LUMO, the HOMO-LUMOenergy gap and triplet energies for each structure were calculated usingDFT calculations with the Gaussian software package at the B3LYP/cep-31gfunctional and basis set. The DFT calculations are summarized inTable 1. Ex. is an abbreviation for Example, Compd. is an abbreviationfor Compound, CC is an abbreviation for Comparative Compound.

Table 1 shows HOMO, LUMO energy levels, the HOMO-LUMO energy gap andtriplet energies for a series of dibenzofuran (DBF) containingheteroleptic carbene complexes, in comparison to homoleptic triscomplexes, i.e., CC1 to CC4. It can be seen in this table from Ex.1 to 9that when one or two DBF containing carbene ligands in a tris complex isreplaced by another carbene complex, for example,

its HOMO energy is raised up in each case while maintaining its T₁energy. The biggest difference of 0.52 eV can be seen in Ex.5 vs. Ex.6.The HOMO of heteroleptic complex 4002 is −5.04 eV, while its tris CC3 is−5.56 eV. Without being bound by theory, it is believed that a higherHOMO energy of an emitter will facilitate the emitter to trap the hole,which can result in better device efficiency and lifetime.

Ex. 10 to 13 are for DBF containing heteroleptic carbene complex withone or two carbene ligands having fused pyridine on imidazole ring. Ithas been unexpectedly shown that the singlet gaps of these compounds(−3.59 to −3.72 eV) are much narrower than that of tris compound (−4.18eV for CC4), and their T₁ energies (448, 449 nm) actually become higherthan that of tris compound (451 nm). This is opposite to the usual casethat the change of singlet gap of a compound will shift at the samedirection as the change of its triplet energy. Without being bound bytheory, with a certain triplet emission energy, the emitter having asmaller singlet energy is highly desired. Lowering the singlet energy isexpected to reduce the likelihood of singlet excited statedecomposition, thereby resulting in improved device lifetimes.

Physical Characterization

Photo physical characterization has been done with inventive complex4003 vs. comparative complex CC1. PMMA and Ir complex (5 wt %) areweighed out and dissolved in toluene. The solution is filtered through a2 micron filter and drop cast onto a precleaned quartz substrate. PLquantum efficiency (Φ_(T)) measurements were carried out on a HamamatsuC9920 system equipped with a xenon lamp, integrating sphere and a modelC10027 photonic multi-channel analyzer. PL transient lifetime (τ_(T))measurements were carried out by time correlated single photon countingmethod using a Horiba Jobin Yvon Fluorolog-3 integrated with an IBHdatastation hub using a 335 nm nanoLED as the excitation source. Allmeasurement was conducted at room temperature, and the results aresummarized in Table 2.

450 87 15 22 CC1

442 71 28Based on the photo physical characterization, it is unexpectedlyobserved that the heteroleptic carbene complex 4003 has much higher PLquantum efficiency, and smaller PL transient lifetime. Without beingbound by theory, a smaller transient lifetime will reduce the chance ofdecomposition and excited state quenching of triplet exciton of theemitter, which will in turn enhance device performance. A higher PLquantum efficiency value of an emitter is desired for a high efficiencydevice performance.

The reaction mixture was bubbled with N₂ for 30minutes and then heated up to 150° C. for 20 hours. The mixture wascooled down and added into water/ethyl acetate. The organic phase waswashed with brine and run through a silica gel plug with ethyl acetate.After removal of solvent, the organic residue was recrystallized fromethyl acetate/hexane to get about 1.8 g (76% yield) white solid for nextstep.

1-Dibenzo[b,d]furan-4-yl)-4-methyl-1H-imidazole (1.2 g, 4.83 mmol) wasdissolved in ethyl acetate (40 mL) in a 250 mL flask. To the mixture,MeI (3.43 g, 24.17 mmol) was added. The reaction mixture was stirred for24 hours at room temperature. After filtration, 1.8 g (95% yield) ofwhite salt was obtained.

A 100 mL round bottom flask was charged with3-methyl-1-phenyl-1H-imidazol-3-ium iodide (16.98 g, 59.3 mmol), silveroxide (6.88 g, 29.7 mmol) and acetonitrile (180 mL) to give a tansuspension. The reaction mixture was stirred at room temperatureovernight. Solvent was removed by vacuum distillation and the residuewas used for next step without purification.

A 100 mL round-bottomed flask was charged with iodide salt (309mg, 0.794mmol), silver oxide (92 mg, 0.397 mmol), and acetonitrile (100 mL) togive a tan suspension. Reaction mixture was stirred in room temperaturefor overnight. Solvent was removed by vacuum distillation and residuewas used for next step without purification.
